NAME

crunchide — hides symbol names from ld, for crunching programs together

SYNOPSIS

crunchide

[-f keep-list-file] [-k keep-symbol] object-file [object-file ...]

DESCRIPTION

crunchide hides the global symbols of object-file such that they are ignored by subsequent runs of the linker, ld(1). Some symbols may be left visible via the -k keep-symbol and -f keep-list-file options. The keep-list-file must contain a list of symbols to keep visible, one symbol per line. The names given by keep-symbol or in keep-list-file should be C names. For example, to keep the C function “foo” visible, the option “-k foo” should be used.

crunchide is designed as a companion program for crunchgen(1), which automates the process of creating crunched binaries from multiple component programs.
